Is Santander New Product a good mortgage choice for first-time buyers in the UK in 2026?

Santander New Product mortgages aim to support buyers saving up for a home or moving along the property ladder in 2026. This guide explains Santander My First Mortgage, low deposit mortgage options, interest rates, affordability checks, and how a mortgage broker can help you apply with confidence.

Santander UK has introduced My First Mortgage, a new option aimed specifically at first-time buyers who are struggling to save a large deposit. The product offers borrowing of up to 98 percent of a property’s value on a five-year fixed rate of 5.19 percent. There is no product fee, and buyers also receive £250 cashbackA sum of money paid by the lender to the borrower as an ince..., helping to reduce some of the upfront costs involved in purchasing a home.

This mortgage is available exclusively to first-time buyers and can only be accessed through a mortgage broker, rather than directly from Santander UK. The bank says this approach is intended to ensure buyers receive advice and understand the long-term commitment they are taking on.

Santander’s own research highlights why this product has been launched now. More than half of UK adults, around 52 percent, say that saving for a deposit is the single biggest barrier to getting onto the property ladder. With house prices remaining high and rent costs continuing to rise, many aspiring homeowners find it difficult to save while also paying monthly rent and household bills.

Under the my first mortgage scheme, buyers need a minimum deposit of £10,000, with maximum lending available up to £500,000.

Mortgage terms can be as short as five years or as long as 40 years, giving borrowers flexibility to manage monthly repayments.

Lending above 95 percent and up to 98 percent loan-to-value is only available on existing houses. Buyers purchasing new-build homes or flats are still limited to a maximum of 95 percent loan-to-value.

As with all Santander lending, applications are subject to full affordability checks. This includes a maximum loan-to-income multiple of 4.45 times salary, along with standard stress testing to ensure borrowers could still afford repayments if interest rates rise in the future.

Commenting on the launch, David Morris, Head of Homes at Santander UK, explained that saving for a deposit remains one of the toughest challenges for would-be homeowners. He noted that last year the average first-time buyer with Santander put down a deposit of more than £85,000, a figure that can feel completely out of reach for many people today. This is especially true for those with modest incomes, limited family financial support, rising rental costs, or additional expenses such as childcare.

Santander mortgage rates for first-time buyers: what affects them?

Santander mortgage rates for first-time buyers are influenced by several key factors, rather than one single rule. The size of your deposit plays a major role, as larger deposits usually unlock lower interest rates. Your overall loan size, chosen mortgage term, and the outcome of Santander’s credit search also matter. Rates are closely linked to movements in the Bank of England base rate, which affects the wider UK mortgage market. Because of this, mortgage rates change regularly and are updated through lender rate bulletins rather than staying fixed long-term.

Affordability checks and stress testing

When assessing a Santander New Product mortgage, it follows the Mortgage charter and financial conduct authority affordability rules. The aim is to ensure borrowers can manage their mortgage not just today, but in the future as well. Santander looks at your income after tax and compares it against everyday spending, including rent costs, household bills, and in some cases business rates. Student loansLoans that are taken out by students to finance their educat... and personal pension contributions are taken into account, alongside existing credit commitmentsAny existing financial commitments, such as credit card or l... and general living costs. Santander also applies stress test rates that are higher than current interest rates to check whether repayments would still be affordable if borrowing costs rise.

Credit profile and lending criteria

Your credit profile is an important part of any Santander new product application. Santander reviews your full credit file, including your payment history, existing debts, overdrafts, and any missed payments. If you already own property, the lender may also consider your past mortgage behaviour to understand how you have managed credit over time. A stable credit history with sensible borrowing patterns generally improves approval chances.

Deposit rules and family support

Most Santander New Product mortgages require a minimum deposit of around 5 to 10%, depending on the property and product. Santander bank usually expects clear evidence that the deposit has been built up gradually through saving. Gifted deposits from the bank of mum and dad are commonly accepted, provided there is written confirmation that the money is a genuine gift and not a loan.

In some circumstances, schemes such as Rent to Own may be considered where permitted by lending rules.

Required documents for a Santander mortgage

To apply for a Santander mortgage, borrowers normally need to provide photo identification and proof of addressEvidence of a borrower's current address, such as a utility ..., along with evidence of income such as payslips or self-employed accounts. Recent bank statementsA record of a borrower's financial transactions often requir... are required to show spending patterns and affordability, and a credit report may be reviewed as part of the application.

If you plan to make lump sums or use overpayment facilities in the future, it can also help to disclose these intentions early. If you want to the exact documents that will be required, you can contact our team of expert mortgage brokers to help you.

Interest only and Buy to Let considerations

Most Santander new product deals are standard repayment mortgages, where the loan balance reduces over time. Interest only mortgage options are limited and typically require a clear repayment strategy, a larger deposit, and acceptance of higher risk. Buy to Let mortgages are assessed under separate criteria and are generally not designed for first-time buyers entering the housing ladder.

The Financial Conduct Authority do not regulate buy to let mortgages.

Are overpayments allowed on Santander New Product mortgages?
